OF, FWIW I used to live in south Texas. It's very sunny and hot there in the summer. A white helmet was way cooler, really the only way to go if you had a choice. Here in VA still better with white. Same for jerseys.

Well certainly for those formerly endowed with hair on top of their noogin, putting a dark coloured radiation sink on what's essentially a solar reflector should make some difference, mitigating effects of ventilation be damned.

I am totally bald and have been rocking a black helmets in the heat of DC for years. Never caused too much of an issue. I have had red/white helmets with bad ventilation that have literally been unbearable in the summer.
